Summary:This study was carried out to determine the susceptibility levels of An. fluviatilis and An. minimus to DDT (4%) and deltamethrin (0.05%) and to select the insecticide to be used for routine national malaria vector control programme based on the results of the susceptibility test. Susceptibility test was done as per standard WHO susceptibility tests using DDT(4%) and deltamethrin (0.05%) in the villages of Keonjhar Districts during 2009. The results indicate that An. fluviatilis showed 100% mortality to DDT (4%) and deltamethrin (0.05%) and An. minimus showed 96.2 per cent mortality to DDT (4%) and 100 per cent to deltamethrin (0.05%). An. fluviatilis and An. minimus have been incriminated as the major malaria vectors of Keonjhar district. Successful application of DDT and deltamethrin could reduce the vector load from this area with consequent malaria control as these two species are found to be highly susceptible to DDT and deltamethrin. Another study as per WHO methodology is further recommended to substantiate the result of this study.
